Article discharge system

An article discharge system that pulls out and discharges some articles from an article group disposed in a container, the article discharge system comprising:

• plural grippers that grip the articles;
• weight acquisition units that acquire weight values of the articles that each of the plural grippers grips;
• and
• a control unit that causes the plural grippers to grip the some articles from the article group disposed in the container and, based on a result of a combination calculation using the weight values of the articles that each of the plural grippers grips, causes a predetermined combination of the grippers to release and discharge the articles,
• wherein during a period after the control unit has caused the predetermined combination of the grippers to release the articles and before the control unit next causes the predetermined combination of the grippers to grip the articles, the control unit implements a zero correction process on the weight acquisition units corresponding to only the predetermined combination of the grippers that were caused to release the articles.
